Apart from the fact he can’t actually prove it without playing for us why do you think he couldn’t score a shitload in a team as good as ours that attack more than them and create more? If anything the only type of goal Kane is unlikely to score is running away from a defence from the half way line. Which is something rarely on for us as teams sit so deep.
We don't play the type of football Spurs do. Dybala (or similar type striker including Salah) are more suited to the style what we play. If youy want a "plan b" striker there are cheaper and better suited alternatives
